I guess I'm wondering what a 75yo is doing flying a fairly large airplane. Was it his personal plane? Was he a pilot for a commuter company? Did the plane have passengers?
I personally know pilots of that vintage who fly stuff in the Confederate Air Force that is a LOT bigger than this plane. It's all their health, not the age. I know 45 year olds that I'd never fly with because of how poorly they take care of themselves.
